DOUBLE-DECKED VEHICLE.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed May 21, 1913. Serial No. 769,030.

To all whom it may concern:

Be it known that I, LUnw1c SPANGLER, a subject of the Emperor ofAustria-I-Iungary, residing at Vienna, Empire of Austria-Hungary, haveinvented certain new and useful Improvements in Double-Decked Vehicles;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to double decked vehicles more particularly tramcars and rail- Way cars running on lines with numerous stations closelyfollowing each other at each of which many passengers enter and leavethe car. The total height of such cars must not in the first instanceexceed a certain limit, and further provision must be made forpermitting the passengers to enter and leave the car and to reach theupper deck from the lower deck and vice versa rapidly and with outinterfering with each other. For this purpose I employ the well knownconstruction in which the floor of the lower deck is located as low aspossible between the axles or trucks and the entrance and exit door ordoors are located in the lower deck between the axles or trucks. FurtherI arrange in the lower deck longitudinal benches at the sides of thevehicles with a longitudinal passage way between such benches leading onthe one hand to a vestibule in front of the entrance and exit door ordoors and on the other hand to the stairs leading from the lower deck tothe upper deck and arranged above the axles or trucks.

My invention consists in the particular construction of the upper deckand in the particular arrangement of the benches in the same ashereinafter fully explained and claimed with reference to the annexeddrawings in which Figure l is a side elevation of a tram car embodyingmy invention. Fig. 2 is a plan of the lower deck. Fig. 3 is a plan ofthe upper deck and Fig. 4: is a transverse section of the same.

The entrance and exit door or doors 2 are arranged between the trucks,3, i and the stairs 1 leading from the lower deck to the upper one arearranged above the trucks.

The benches 5 of the lower deck are arranged lengthwise with their backsat the sides of the car with a central longitudinal passage way betweenthem which leads from the vestibules provided in the lower deck in frontof the entrance and exit door or doors 2 to the stairs. In the upperdeck there are provided above the vestibule benches 9 arrangedlengthwise at the side walls of the car with a passage way 10 betweenthem. Between the benches 9 and the stairs l lengthwise benches 6 areprovided with their backs opposing each other, longitudinal passage ways7 being left at both sides of this double bench. These passage ways 7communicate with the central passage way 10 by spaces left between thebenches 9 and 6. Each of the stairs 1 leads into one of the lateralpassage ways 7. The floor of the upper deck is cut away or suitablyraised below the benches 6 in the well known manner whereby the clearheight of the central passage way of the lower deck is increased. Thecentral portion of the upper deck might be provided with transversebenches or a single central longitudinal bench below which latter thefloor of the upper deck might be raised the same as below the doublebench 6.

In the central portion of the car the re quired clear height of thelongitudinal passage way of the lower deck is secured by the fact thatin this portion the floor of the lower deck is drawn down between thetrucks as shown. A step 8 is provided between the central portion andthe end portions of the floor of the lower deck as owing to the trucksthe latter must be on a higher level than the former.

For reaching the upper deck the passengers entering the vestibule in thelower deck go through the central passage way of the same to one of thestairs 1 (for instance the front one) and over the same to thecorresponding lateral passage way 7 of the upper deck to the desiredseats. The passengers leaving the car may go down the other stair (forinstance the rear one) which they reach through the correspondinglateral passage way 7. In order to enable the passengers to go theseways without interfering with each other the passage ways 7 of the upperdeck must be of suflicient width which may be realized by making theupper deck of the car more wide than its lower deck. Now the width ofthe car must not exceed a predetermined limit as in the case of doubletrack two cars could not pass simultaneously a curve in oppositedirections. Therefore I make the width of the upper deck smaller in thecentral portion of the car than at its ends. This is attained withoutaffecting the free passage of the passengers within the car by arrangingthe benches 9 in the central part of the upper deck at the walls of thecar where the central passage way 10 is just as wide as the centralpassage way of the lower deck and quite suflicient for the free passageof the pas-e sengers while at the ends the required width of the.lateral passage ways 7 is obtained by increasing the width of the upperdeck of the ear.

If the stairs are two fiighted as shown, the floor of the upper deckmust be cut away over the bottom flight as shown. One half of thecentral bench must be correspondingly shorter or it must be bent atright angles as illustrated. But the stairs might be straight andarranged transversely to the car and provided with separate entering andexit doors and outer steps leading thereto. Thereby the space availablefor seats is increased and the entrance and exit doors for the two decksare separated from each other. The stairs I might also be so arrangedthat both lateral passage ways 7 and the seats on the double benches 6are freely accessible directly from the stairs, whereas as shown in thedrawings one-half of each of the double benches 6 is accessible onlyfrom the center of the upper deck and hence it is suflicient to makeonly one of the lateral passage ways 7 at each end of the upper deckwide enough for a free passage to the stairs. This may be realized inthe arrangement above described at the ends of the car by suitablyincreasing the width of the upper deck and at the central portion bysubstituting for the double bench a single central bench as aboveindicated, thereby providing lateral passage ways. In order tofacilitate the communication between the lateral passage ways 7 and thecentral passage way 10 notwithstanding the reduced width of the upperdeck in its central portion I may locate at the end of the longitudinaldouble benches 6 a transverse bench 6 below which the floor of the upperdeck is cut away. I thereby prevent the communication between the innerends of the passage ways 7 and the central. passage way 10 from beingimpeded by the feet of the passengers at the inner end of the bench 6.

What claimed is 1. In a double decked vehicle the combination of wheelssupporting the ends of the vehicle, a lower deck and an upper deck, the

gitudinal double benches with their backs opposing each other in the endportions of the upper deck, lateral longitudinal passage ways on bothsides of such double benches, such lateral passage ways communicatingwith the central passage way of the upper deck and at least one of suchlateral passage ways communicating with the stairs, the width of theupper deck being greater at the said end portions than at its centralportion, and the floor of the upper deck being cut away under the saiddouble benches.

3. In a double decked vehicle the combination of a lower deck and anupper deck, longitudinal benches at the sides of the vehicle in thelower deck, a longitudinal passage way between such longitudinalbenches, stairs from the lower deck to the upper deck beginning at theends of such passage way, benches in the central portion of the upperdeck, a longitudinal passage way between the last named benches,longitudinal double benches with their backs opposing each other in theend portions of the upper deck, trans verse benches at the inner ends ofsuch double benches, the length of such transverse benches beingsubstantially equal to the width of the double benches, laterallongitudinal passage ways on both sides of such double benches andtransverse benches, such lateral passage ways communicating with thecentral passage way of the upper deck and at least one of such lateralpassage ways communicating with the stairs, the width of portions, andthe floor of the upper deck being cut away under the said double benchesand transverse benches.

In testimony whereof, I atiiX my signa- ARTHUR GAUMANN, AUGUST .FUeena.
